"1 Reason. First, to hold conformity with the rest of his works, being delighted to show forth the glory of his wisdom in the variety and difference of the creatures, and the glory of his power in ordering all these differences for the preservation and good of the whole; and the glory of his greatness, that as it is the glory of princes to have many officers, so this great king will have many stewards, counting himself more honored in dispensing his gifts to man by man, than if he did it by his own immediate hands."
